Dichotic listening (DL) is the most frequently used method to study language lateralization. The current study investigated the effect of voice-onset-time (VOT) in dichotic listening with consonant-vowel (CV) syllables. Eighty-nine subjects with normal hearing and overall right-ear-advantage (REA) were tested with a PC version of the DL test. Voiced and unvoiced stop-consonants were used in com...

Dichotic listening (DL) tests are among the most frequently included in batteries for the diagnosis of auditory processing disorders (APD) in children. A finding of atypical left ear advantage (LEA) for speech-related stimuli is often taken by clinical audiologists as an indicator for APD. However, the precise etiology of ear advantage in DL tests has been a source of debate for decades. It is ...

Normative data from 24 right-handed and 24 left-handed subjects were obtained for the dichotic consonant-vowel (CV) materials (pa, ta, ka, ba, da, and ga) recorded on the Veterans Affairs (VA) compact disc (CD) Tonal and Speech Materials for Auditory Perceptual Assessment, Disc 1.0. Identification performance by the two subject groups was significantly different. With the right-handed subjects,...

We examined two commonly used dichotic listening tests for measuring the degree of hemispheric specialization for language in individuals who had undergone cerebral hemispherectomy: the consonant-vowel (CV) nonsense syllables and the fused words (FW) tests, using the common laterality indices f and lambda. Hemispherectomy on either side resulted in a massive contralateral ear advantage, demonst...
